Collision File Editor II

Collision File Editor II, the successor of the popular CollEditor, is a tool for creating and editing collision files (*.col) for GTA III, Vice City and San Andreas.

Built completely from scratch, CollEditor 2 is much more reliable and flexible, and offers a lot more features than the old one. It fully supports all characteristics of all 3 known .col file formats, and offers several built-in optimization routines to achieve best possible results.

This program is freeware and can be distributed freely, provided that the distribution is complete in its original unmodified state, including all documentation, copyright notice, disclaimer, and other materials provided with the distribution.

Note: If you download CollEditor II from one of the official sources, you can be sure the package is up-to-date, complete, and correct. However, you could use the following checksums to validate your download, in case you're paranoid:

Known Problems

There is no undo or backup function yet, the only way to restore a collision file is by loading the previously saved version. So don't forget to save and backup your work often! A snapshot function is planned.

The calculated bounding sphere is not minimal at all! Would be great if someone could point me to a (working) implementation of a minimum sphere of spheres algorithm. Speed doesn't matter since it's not done in realtime, but it has to work in RÂ³.

It's not possible to delete vertices (yet), just delete the faces. (Isolated verts will be deleted automatically on saving.)

It's not possible to move faces, just move the vertices used by the face (same effect).

There is no options dialog yet. If you need to change something that's not available through the menu, please edit the CollEditor2.ini by hand.
